Yes, ask him! You'd be surprised how happy your professors are when they are able to help.

I once had a professor who was the ex-CEO of a hospital. I wanted to get into Health Administration, so I asked him about it. You wouldn't believe the advice he gave me. He was an awesome man. I tried to keep in touch, but he passed away shortly after.

Same experience with a law professor. He talked me out of going to law school, probably more because he didn't like his law career, but he wanted to help.
